A slightly less weak pistol then. I honestly see no reason for me to give up my AA, sprint, primary weapon, grenades or power weapon if I have one. 343 says they want to make the flag carrier feel like a bad-ass but to me it seems like the flag carrier is handicapped more than anything. Even with a more powerful magnum (I'm guessing they'll just make it so it's one shot less to kill or something, nothing ground breaking) you'll still be limited in movement and everyone on the map will see exactly where you are.They just said they're still tweaking damage on the pistol.
But ignore that to make a witty comment.
So yeah, someone else can pick up the flag, I'll most likely be steering clear of it.
